Cassini Shapes First Global Topographic Map of Titan
These polar maps show the
first global, topographic mapping of Saturn's moon Titan, using data
from NASA's Cassini mission. To create these maps, scientists employed a
mathematical process called splining, which uses smooth curved surfaces
to "join" the areas between grids of existing topography profiles
obtained by Cassini's radar instrument.Image credit:

Titan is Saturn's largest moon - at 1,600 miles (2,574 kilometers) across it's bigger than planet Mercury - and is the second-largest moon in the solar system. Scientists care about Titan because it's the only moon in the solar system known to have clouds, surface liquids and a mysterious, thick atmosphere. The cold atmosphere is mostly nitrogen, like Earth's, but the organic compound methane on Titan acts the way water vapor does on Earth, forming clouds and falling as rain and carving the surface with rivers. Organic chemicals, derived from methane, are present in Titan's atmosphere, lakes and rivers and may offer clues about the origins of life.
